Description
MS3D Roof Sensor—a component designed to work with the Associated Controls MS3D solar controller for pool heating systems. The version with a 20-metre lead is ideal for installations where the controller is located far from the roof sensor point.
🔧 About the Error Code “RRR” When the MS3D controller displays “RRR”, it typically indicates a roof sensor fault—either the sensor is disconnected, damaged, or has failed. Replacing the sensor with a compatible one (like the 20m lead version) usually resolves this issue.
